Introduction to PI Interface for Random Simulator Data

PI Interface for Random Simulator Data is a 64-bit interface that is used with Data Archive and is an excellent source of test data. Points can be configured to generate various types of randomized data.

Before getting started, it is useful to know the following:

• Install kits

  Prior to PI Server 2018 SP3, PI Interface for Random Simulator Data and PI Interface for Ramp Soak Simulator Data were installed automatically with every Data Archive installation. In doing so, these two data simulators were installed on the same computer as Data Archive, and default PI points were created as part of the installation. Beginning with PI Server 2018 SP3, these interfaces are no longer installed automatically, but rather are available as separate install kits for all users. PI points must be created manually. See Create default PI points.

• Random .csv

  Included in the setup kit for PI Interface for Random Simulator Data is a .csv file, which provides examples of the configuration required for user-created default tags in the .csv file. Open the file to view the PI point attributes for the following example point types:

  • Int32:

    • CDEP158

  • Digital:

    • CDM158

  • Float32:

    • CDT158

    • SINUSOID

    • SINUSOIDU

• Setup is operating system dependent

  The value of [PIHOME] variable for the 32-bit interface will depend on whether the interface is being installed on a 32-bit operating system (C:\Program Files\PIPC) or a 64-bit operating system (C:\Program Files (x86)\PIPC).

  The value of [PIHOME64] variable for a 64-bit interface will be C:\Program Files\PIPC on the 64-bit operating system.

  In this documentation [PIHOME] will be used to represent the value for either [PIHOME] or [PIHOME64]. The value of [PIHOME] is the directory which is the common location for PI client applications.
